Justification:
Listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat on the Serra de Maranguape.

This is a diurnal species that lives in the leaf-litter of primary and secondary forest, and has also been found in bamboo and banana plantations, as well as forest fragments (but not open habitats). It is a direct developer, and the eggs are probably laid on the ground.
